- ingthe relation of the chains thereto illustrate --the manner in which the shaking effect is produced on articles carried on said chains. .Fig. 5 I is I view through one having trays or molds filled, with confections in the provision of means for lightl brushing the surface of the confections uring the whereby a superior oli shed-eifcct may be imparted to the sur-' ace thereof. s Theinvention is fullyillusltrated in the ac shown in Figs. 3' and 4, are so constructed as to provide projections 12 thereon at regular intervals on the contiguous surfaces thereof, these preferably being I link having-a rounding'hook on'the end to engage with the contiguous link .of the chain, as clearly illustrated in the drawings referred to, the rounded ends of the hooks extending Figure 1' is a top plan view of the machine inwhich theinvention is embodied. Fig. 2 is a side elevation of the same,;the, chains preferably being rectangular in shape, The inks being mounted on the sprockets, the bearings a and f of the shafts 0d are so adjusted as to place the chains 1' and 8 under a proper tension. It will be noted that-the shafts c and d and 0 cl are connected together in a manner which if one of, the gears j or g barotated movement will be imparted to' the chains 1" and s in opposite directions, whereby the projections v on the chain will ride over the projections on theother, the alternate positions of the links of the two chains being shown in Figs. 3 and 4, whereby anything placed on the chainwill be given a vertical reciprocating jarring movement equal to the height of the two projections on the two chains, and the frequency of the vi brations may be regulated as desiredby the relative speeds of the chains, these, as stated, running in opposite directions.

, To provide w,.which are ing through the machine and constituting being shown in dotted lines only. Figs. 3 and 4 are side elevations of the chains in two-different posi-' tions and on an enlarged scale and clearly a fragmentary sectional of the side rails of the machine, substantially on line 5 5, .Fig. '1, show- Fig. 6 showing a portion of one is a side elevation of the shaking-table and of the end frames which the shaking-table is used, the latter delivered to it from the molding-machine.

Referring now ,to the drawings, a b indicate two end frames spaced at suitable dis-v tances apart by the rails b each frame carryin two shafts located in the same horizonshown in Figs. 1 and 2, on the tal p ane, the shafts in the frame a being indiformed by making a I citizen of the United States of America, re' which are adjustable independentl' in the siding at Springfield, in the county of Hamp-i same plane toward and from the s afts c den and Stateof Massachusetts, have in' and (1. so T I Q l vented ew and useful Improvements in. j .On the shaft 0 is a large gear g, andon'the It is to benoted that these chains, as i beyond the plane of the links,' the latter for carrying the trays or molds chain 8, which is the outer chain, trans-' cated by c and d and those in the frame I) b versely-located bars as are secured to the latc and d. The shafts in the frame bare pre ter, .as shown in Fig. 2, and on the under side trays move ed to of the trays are bars or cleats y, fit in between two of the bars :20,

tray may be carried along with the chain positively. This is shown and described only as a desirable mode of engaging the trays or molds with the chain, and, if desired, a different means of engagement may be provided.

Any device for imparting movement to the shafts c and d and c and d in the manner described may be employed but I prefer to use the gears connected in the manner described with said shaft and with each other, and to drive one of the gears g or j a driving-shaft 3 is mounted in the frame a and provided with a small gear 4 to mesh with the gear 9, the shaft 3 having a driving-pulley 5 thereon, and, as shown in Fig. 1, a clutch 6 is located between the driving-pulley and the gear 4, whereby by means of a clutch-lever 7 the machine may be stopped or started at will.

To support the chain between the two frames (1 and b, the side rails b are made of channel-iron, their flanges extending inwardly, as shown at 9 9, Fig. 1, whereby they may serve asa. shelf to support the chains and prevent their sagging, it being undesirable to tighten the chains sufliciently to carry the trays to through the machine in a substantially horizontal plane without permitting them to sag, for the reason that under such conditions the strain on the bearings of the shafts c c and d d would be too great.

adapted to whereby the To impart the highest finish to the surfacev of the confections in the compartments 8 of the tray to, it is desirable that the exposed surfaces thereof be brushed lightly as the through the machine. To this end a suitable standard 10 is mounted on one side of the machine, preferably near the delivery end of the latter, and on this is carried an arm 12, pivotally mounted on the standard 10 to swing in a horizontal plane, one end of the arm which extends outside of the standard being by means of a rod 13 connecta cran -pin 14, carried on the gear g, whereby reciprocating movements in a horizontal plane may be imparted to the arm 12. On the end of this arm, which extends about half-way across the tray w, is a cross-arm 15, extending both sides of the arm 12 substantially at right angles thereto and carrying on the under side of the opposite ends thereof brushes 16, so positioned that their ends will sweep lightly across the exposed surface of the confections in the compartments of the tray to, the swing of the arm 12 being illustrated in Fig. 1 by the dotted position thereof, whereby it is seen that each of the brushes 16 will swing from side to side of the trays as the latter pass under them. I

In practice the machine forming the subject-matter of this application is used in connection with a machine for filling molds with paste confectionery, more especially chocolate, of which that forming the subject-matter of my prior United States Letters Patent for paste-molding machines, dated December 12, 1905, No. 807,107, is ag'ood type, and in Fig. 6 of the drawings a portion of said machine is shown, 17 indicating the table thereof on which the trays or molds w are supported during the mold-filling operation, as described therein, and which by the movement of the mold-fllling machine are delivered onto the chain belt 8 of the shaking-table.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. A shaking-table consisting of a flexible carrier having downwardly-extending projections thereon, a support for the carrier provided with upwardly-extending projections, and means to move the carrier over its support to cause the projections thereon to ride over the-projections on the support.

2. A shaking-table consisting of a flexible carrier having downwardly-extending projections thereon, a movable support for the carrier provided with upwardly-extending projections, and means to move the carrier and its support in opposite directions to cause the projections on the carrier to ride over those on the support.

3. A shakin -table consisting of a flexible carrier, and a exible support, the latter and the carrier having oppositely-extending projections, and means to move the carrier and itssupport in opposite directions, the path of movement of the projections on one of said elements extending into the path of movement of the projections on the other.

4. A shaking-table consisting of two endless chains, the outer one constituting a carrier, said chains being movable in the same plane with the under side of one in contact with the upper side of the other each being provided with projections on their contiguous sides, and means to move the chains in opposite directions.

5. In a shaking-table, a suitable frame, two shafts supported in each frame substantially in the same plane, s rocket-wheels fixed on the ends of each sha t, those on the outer shafts at each end of the frame having a greater diameter than those on the inner shafts; chains running over said sprockets the inner surface of one being in contact with the outer surface of the other, there being projections on the contiguous surfaces of the chains, together with means to adjust said shafts toward and from each other, said jections on the support, together With a brush supported above the carrier to lightly brush the surface of a tray or mold moving through the machine on the carrier.

7. shaking-table consisting of a flexible carrier and a support for the carrier, there being projections on the contiguous surfaces of the carrier and the support, means to move the carrier over its support to cause the projections thereon to ride over the projections on the support, together with a brush supported above the carrier to swing over the surface of a tray or mold moving through the machine on the carrier, and a suitable mechanism to actuate the brush by the movement of the machine.

8. In combination a shaking-table consisting of a flexible carrier having downwardly-extending projections thereon, a support for the carrier provided with upwardlyextending projections, and means to move the carrier over its support to cause the projections thereon to ride over the rojections on the su port, said carrier receiving trays or molds iil ed with paste confections, together with a brush-o eratively located above the carrier to brus the'surface of said confections.

9. In combination a shaking-table operatively located to receive trays or molds filled with confections in a paste form, and a brush supported abovesaid shaking-table to sweep the surface of the mold during the movement of the latter over said table.
